Ask HN: Use case diagram, how to do better?
Ministry of Health and Population is willing to computerize its system. This new system will be able to tell the population of the country, zone, and district and even ward of the specific place. The system will update its data in monthly basis so that the birth rate and death rate can be easily seen. The home page is displayed when a person enters to the system. Administrators can enter to the system by logging in with an ID and a password. he/She has privileges to enter and modify the data into the database. On the other hand, normal users can vview the data but not modify them. They can also visualize the data in graphical form, maps as well as tabular form. Besides they can also view the forecasted data.
How I thought through this:
There is a user:
For an admin user, there is authorization required.
For a normal user, no authorization is required.
A normal user can:
- view population data and that too in various forms of visualization like graphical, tabular, maps etc.
- view forecasted data
An admin user can:
- once logged in
- do all the activities that a normal user can
- and also be able to update+modify the data.
